HAYRACK UNLQADERQ (GRANTED UnDEn rHErnovIsroNs or rnnca'oror nancnra, 1921, 41 ST/AT. I.., 1318.)

To all w/wnm't'may concern, Y

Be it kn jlwn that I, Vroron GILBERT OUELLETTE, a subject of. the Kingof Great I Britain, of the townof Clodford,Province. of Alberta, Canada, have inventedce'rtain new and useful Improvements in Hayrack Unloaders, (for which I'have filed applicationin Canada, August 19, 1919 patentissued June 15, 1920, No. 200,987),of whichthe following is a specification.

My invention relates to improvements in hay rack unloaders, and the object ofthe invention is to permit the hay rack to be unloaded from a wagon gear by one man, and. without any danger ofbreakage, and without any appreciablellabour onthe part of the man, and in the following specification, I shall describe an embodiment-of my ins vention, and the mannerin which the same operates and what I claim as new will be set I forth in the claims forming partof this specification. f I

Figure 1 is a perspective view. of the ma jor portion of my preferred form o f hay rack unloader, the same-being positioned to receive the hay rack. Figure 2 a side elevation of my hay rack unloader showing the same supporting the front of the hay rack above the wagon gear (not shown). Fig. 3 is a side elevation of my hay rack hay rack clear of the wagon gear (not shown), and- Flg. 4 1s a vertical crosssection on the line 2--2, Figure 2.

,In the drawings, like characters ofreference refer to the same parts. a

It is well-known that particularly in farm work, a. hay rack frequently has to here moved from thewagon gear, and that in order to perform this work, it has heretofore been necessary to'secure the labour of several men, and even then sometimes through carelessness breakage is caused. Now in putting my inventionvinto practice, I. conveniently locate and support two members, or skids so associated that when the wagon is driven therebetween, in duecourse one end of the hay, rack comes in contact with said. members or skids, and'as the wagon pro gres ses, the said members or skidsare raised up, thus lifting the front of the rack off the wagon gear. Thesaid members or skids are so balanced that when the driver walks towards the upper end of the rack, the lower.

I end of apparatus is elevated and propped in pos tion and the apparatus held against backwardmovement, thus omtented Feb 7, 11922 7 I Itwill, of course,fbe understood that as the front end of the rack is being lifted,

the back "part thereof fisstill supported by the wagon gear sothat the movement of the wagon may betransmitted to the rack for'tlie purpose'of permitting the appar t to perform. its first operation, that of partly lifting the rack off. the wagon gear.

'Obviously, my invention may be used gto ois unload other objects from off a wagon gear,

of my invention. I a

Aand B are a. pair of skids normally supported in an inclinedf'position and, having. theirlower ends tapered, as shown at a to prevent'the 'skids at this timerbeing moved by said rack. 'By any suitable means such as arms C and D, the said skids are mov-I E; and F that the skidsgA and B-normally 'rest. The supports E and F are shown as orsleigh, without departing from the spirit driven into thei ground, and are tied together 'suitably' by bars bracedj by the braces their fefspectiveskids A andB by means of bolts 2, and I prefer to'pivot the lower ends of the. said arms to their respective supports E by bolts 3.. Suitably associatedfwith the lower ends of theskids A and B are suitable prop members. These prop members are preferably in pairs and are formed of bars 4 and owhich are coupled together at their I prefer to pivot the arms C and D to G, and suitably bar-s4; and 5 are suitably associatedwith skids A and B to secure the required'movement as by means of bolts 7. Upon referring to thed-rawings it will be observed that the.

supports E are preferably inclined from the vertical and that the arms C and D will rest thereag'ainst as shown clearly in Figure 4,

' and prevent the skids A and B from falling when elevated. 8 are a pairof pins or other suitable stops, preferably remov'ably carried by the skids A and B. When a wagon is driven between the said skids, the front cross-,member 9 of the, rack 10 will come in contact with said stops, and during the continued moving of the wagonftheskids A and B will be elevated until the arms D'; reach the vertical, thus completely lifting' the rack; except at its lower end, above the wagon gear "(not 'shown).' so o'n aslthe forward'portion of "the rack is elevated the" wagon is :brough't'to rest; and then the driver walks towards the upper or forward end of therack beyond the bolts 2, and moves'the skids around these bolts, thus lifting the lower end of the rack off the wagon gear. During .tlie movement just described, the bars 4: and are raised up, and swung'by gravity around their bolts 7 bringing the bolts 6*above the supports 'l1, which' s1ip .por ts ultimately support saic barsyas the driverwalks forward to tilt the lower end has of the apparatus, he moves the'arms C and D out of the vertical so that when. the ap-' par'atus ultimately assumes the position illustrated in Fig. 3; there will beno dangersof'the ski'nds A and B falling.

, In orderto replace the hay rackon the wagonfgear, the wagon is run in between the skids Aland B, and when properlylocated, the bars-it and: 5 are removed from the supports llandlo'rought into the position illustrated in l igv 2,v thus lowering the'rear of the rack upon the wagon gear. The wagon is then move d backward until the skids A? and B are carried by the supports E and'F, and then after removing the stops 8, the wagon isdriven from'jbetween the skids A and B without the rack 'beinglifted.

I It will b e un'derstood by one skilled in this art, that the apparatus herein disclosed isv one that can'be built out of different kinds of lumber; orother suitable material, and

while it will be relatively cheap to manu .facture, still itf willibe very durable and:

strong;
